INDUCTION SYSTEMTHROTTLE VALVE ACTUATOR
The throttle actuator is actuated by the Engine ControlModule (ECM) according to the position of theaccelerator pedal position.
It has two potentiometers which signal the position ofthe throttle valve to the ECM to enable it to recognizethe various engine load states.
Ignition “Off”In the de-energized states the throttle valve positionis determined to be spring capsule.
Ignition “On”When the ignition S/W on the servo motor in the throttleactuator is operated by the ECM. The throttle valveadopts a position in line with the coolant temperature.
Closed positionIn the closed throttle position, the servo motor controlsengine speed by operating the throttle valve further(greater mixture) or closing it further (reduced mixture),depending on coolant temperature and engine load.When this is done, the throttle valve can be closedfurther by the servo motor overcoming the force of thespring capsule (mechanical end stop). If the actuatoris de-energized, the throttle valve is resting against
YAA1F540
the spring capsule.
Consequently, the throttle valve opening is a constant10-12 °approximately.
At no load, this produces an engine speed of about1,800 rpm
DrivingWhen driving (part/full throttle), the servo motor controlsthe throttle valve in line with the various load statesand according to the input signals from the pedal valuesensor according to the input signals from the pedalvalue sensor according to the posit ion of theaccelerator pedal.
The function of the EA (electronic accelerator) in theECM determines the opening angle of the throttle valvethrough the throttle actuator. Further functions are;
• Idle speed control
• Cruise control
• Reducing engine torque for ASR/ABS operation
• Electronic accelerator emergency running
• Storing faults
• Data transfer through CAN

Circuit Description
The ECM supplies a 5 volt reference signal and a ground to the TP sensor. The TP sensor sends a voltage signalback to the ECM relative to the throttle plate opening. The volt age signal will vary from approximately 0.3 ~ 0.9volts at closed throttle, to over 4.0 ~ 4.6 volts at Wide Open Throttle (WOT).
The TP sensors serve for engine load control according to the drive pedal command. Load adjustments independentof the drive pedal command can be implemented; such functions are, for instance, idle control, speed control,drive slip control, load shock damping, and similar functions .
When the actuator current fails , the throttle valve is returned to emergency operating position by a spring. Thethrottle valve position, there by the actuator drive position check back is provided by two potentiometers. Themotor positions the throttle valve against the return spring force. Motor and return spring are two separate energysources . Each of them is able to position the throttle valve in emergency position alone. Throttle valve positioncheck back and monitoring is provided by two actual value potentiometers connected to the engine controlelectronics.

HOT FILM AIR MASS (HFM) SENSOR
YAD1F430
The Hot Film Air Mass (HFM) sensor with recognition of flow direction related to pulsating flow is designed forrecording load on Engine Control Module (ECM) by measuring the output voltage proportional to the referencevoltage of the ECM.
Mass Air Flow SensorMass Air Flow (MAF) is a thermal flow meter whose sensor element with its temperature sensors and heating areais exposed to the MAF to be measured. A heating area located in the center of a thin membraneis controlled to anover temperature by a heating resistor and a temperature sensor of this membrane. And the value of over-temperature depends on the temperature of the in-flowing air.
Two temperature sensors on upstream and downstream of the heating area show the same temperature withoutincoming flow. With incoming flow, upstream part is cooled down but downstream temperature retains its temperaturemore or less due to the air heated up in the heating area. This temperature difference in quantity and directiondepends on the direction of the incoming flow.
ECM modulates the flow of heating current to maintain the temperature differential between the heated film andthe intake air at a constant level. The amount of heating current required to maintain the temperature thus providesan index for the MAF. This concept automatically compensates for variations in air density, as this is one of thefactors that determines the amount of warmth that the surrounding air absorbs from the heated element. MAFsensor is located between the air filter and the throttle valve.

Intake Air TemperatureThe Intake Air Temperature (IAT) sensor is a part of Hot Film Air Mass (HFM) sensor and is a thermistor, a resistorwhich changes value based on the temperature of theair entering the engine. Low temperature produces a highresistance, while high temperature causes a low resistance as the following table.
The ECM provides 5 volts to the IAT sensor through a resistor in the ECM and measures the change in voltage todetermine the IAT. The voltage will be high when the manifold air is cold and low when the air is hot. The ECMknows the intake IAT by measuring the voltage.
The IAT sensor is also used to control spark timing when the manifold air is cold.
Under high fuel demands, the MAF sensor reads a high mass flow condition, such as Wide Open Throttle (WOT).The ECM uses this information to enrich the mixture, thus increasing the fuel injector on-time, to provide thecorrect amount of fuel. When decelerating, the mass flow decreases. This mass flow change is sensed by theMAF sensor and read by the ECM, which then decreases the fuel injector on-time due to the low fuel demandconditions.
To facilitate the installation of the HFM in the intake passage, lubricating agents may be used. However, whenlubricants are used care must be taken to ensure that they do not enter the flow passage and cannot be suckedin with the air flow.
The following tables show the relationship between MAF and output voltage.

Circuit Description
The heated element on the MAF is a platinum film resistor (heater). It is located on a ceramic plate together withthe other elements in the bridge circuit. The temperature sensitive resistor (flow sensor) also included in thebridge. The separation of heater and flow sensor facilitates design of the control circuitry. Saw cuts are employedto ensure thermal decoupling between the heating element and the intake air temperature (IAT) sensor. Thecomplete control circuitry is located on a single layer. The voltage at the heater provides the index for the massair flow. The MAF’s electronic circuitry then converts the voltage to a level suitable for processing in the ECM.This device does not need a burn off process to maintain its measuring precision over an extended period. Inrecognition of the fact that most deposits collect on the sensor element’s leading edge, the essential thermaltransfer elements are located downstream on the ceramic layer. The sensor element is also design to ensure thatdeposits will not influence the flow pattern around the sensor.
The IAT sensor uses a thermistor to control the signal voltage to the ECM. The ECM supplies 5 volt reference anda ground to the sensor. When the air is cold, the resistance is high; therefore the IAT signal voltage will be high.If the intake air is warm, resistance is low; therefore the IAT signal voltage will be low.

ENGINE COOLANT TEMPERATURE (ECT) SENSOR
YAA1F590
Engine Coolant Temperature (ECT) sensor detects coolant temperature and supplies information to the ECM. It iscomposed of metal housing with two NTC resistor, 4 pin connector. The ECM provides a 5 volt signal to the ECTsensor through a dropping resistor. When the engine is cold, the ECT sensor provides high resistance, which theECM detects as a high signal voltage. As the engine warms up, the sensor resistance becomes lower, and thesignal voltage drops. At normal engine operating temperature, the ECT signal will measure about 1.5 to 2.0 volts.
The ECM uses information about coolant temperature to make the necessary calculations for:
• Fuel delivery
• Ignition control
• Knock sensor system
• Idle speed
• Torque converter clutch application
• Canister purge
• Cooling fan operation
• Others

The Acceleration Pedal Position (APP) sensor is mounted on the accelerator pedal assembly. The sensor isactually two individual APP sensors and one housing. This sensor works with theThrottle Position (TP) sensor toprovide input to the Engine Control Module (ECM) regarding driver requested accelerator pedal and throttle angleat the throttle body.
When the APP sensor is defected:When the APP 1 or APP 2 sensor is defected condition, the engineis still running at idle condition but, theaccelerator pedal reaction is not response correctly and also, the engine rpm will be reacted to 4,000 rpm slowly.If the APP 1 sensor is out of order, the APP 2 sensor will be conducted with signal as adefault signal but, thethrottle valve opening is limited 60% and delayed opening speed.
When the TP sensor or servo motor is defected:When the TP 1, 2 sensor or servomotor is defected condition, the throttle valve will be closed to the springcapsule by spring force, at this condition, the throttle valve will open 10° ~ 20° and engine rpm will be controlledby ECM will opening (On/Off) time of injector. The engine rpm will be maintaining 900 rpm (at idle) to 1,800according to the engine load.

EXHAUST SYSTEMCATALYTIC CONVERTER
The purpose of the catalytic converter is to convertthe three pollutants of carbon monoxide (CO),hydrocarbons (HC) and oxides of nitrogen (NOx)contained in the exhaust of gasoline engines, into theharmless compounds of water (H2O), carbon dioxide(CO2) and nitrogen (N2).
The catalytic converter contains acatalyst, a wordcoming from the Greek and which designates theelement essential for catalyst which triggers chemicalreactions without itself being consumed.
These catalysts in the 3-way catalytic converter arethe rare metals platinum (Pt) and rhodium (Rh).
The catalytic converter consists essentially of threemain elements. The exhaust gases flow through thecatalytic converter and, in so doing, coming intocontact with rare metals (Pt and Rh).
The following chemical reaction are produced.
CO + O2 → CO2
HC + O2 → CO2 + H2O

OXYGEN SENSOR
YAD1F570
The oxygen sensor is unique amongthe engine controlsensors because is acts like a battery and is able togenerate its own low voltage signal. It is located theexhaust system and monitors the amount of oxygen inthe exhaust stream and provides feedback to theEngine Control Module (ECM).
The electrically heated oxygen sensor warms up quicklyand remains hot, even at idle when the exhaust manifoldmay cool down.
The ECM applies a reference voltage of 450 mv to theoxygen sensor, the ECM compares this referencevoltage with the voltage generated by oxygen sensor.The amount of voltage the oxygen sensor generates isproportionate to the difference between the amount ofoxygen in the outside air and the exhaust gases. Theatmosphere contains about 21% oxygen. The exhaustfrom a rich air/fuel ratio contains almost no oxygen.With a large difference betweenthe amounts of oxygencontaining the two surface, the sensor generates lessvoltage.
YAD1F580
When the exhaust gas is rich (below 14.7:1), the voltageoutput is high, above 450 mv. When the exhaust gasis lean (above 14.7:1 air/fuel ratio), the sensor’svoltage output is low, below 450 mv.
The ECM uses oxygen sensor information for:
• Open loop / closed loop criteria
• Ideal air / fuel ratio

Circuit DescriptionIn order to control emissions, a catalytic converter is used to covert harmful emissions into harmless water vapor andcarbon dioxide. The ECM has the ability to monitor this process by using a oxygen sensor. The oxygen sensorproduces and output signal which indicates the storage capacity of the catalyst. This in turn indicates the catalyst’sability to convert exhaust emission effectively. If the oxygen sensor pigtail wiring, connector, or terminal is damaged.Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly, it must havea clean air reference provided to it. This clean air reference is obtained by way of the oxygen sensor wire(s). Anyattempt to repair the wires, connector, or terminal and degrade the oxygen sensor performance.

ENGINE CONTROL MODULE
YAD1F610
The Engine Control Module (ECM), located inside the right side kick panel, is the control center of the fuelinjection system. It constantly looks at the information fromvarious sensors and controls the systems that affectthe vehicle’s performance. Engine rpm and air mass are used to measure the air intake quantity resulting in fuelinjection metering. The ECM also performs the diagnostic functions of the system. It can recognize operationalproblems, store failure code(s) which identify the problem areas to aid the technician in making repairs.
There are no serviceable parts in the ECM. The calibrations are stored in the ECM in the Programmable ReadOnly Memory (PROM).
The ECM supplies either 5 or 12 volts to power the sensors or switches. This is done through resistance in theECM which are so high in value that a test light will not come ON when connected to the circuit. In some cases,even an ordinary shop voltmeter will not give and accurate reading because its resistance is too low. You mustuse a digital voltmeter with a 10 Mohm input impedance to get accurate voltage readings. The ECM controlsoutput circuits such as the ignition coils, the fuel injectors, the fuel pump relay, the camshaft actuator, thecanister purge valve, etc., by controlling the ground circuit.

Circuit Description
The provision for communicating with the ECM is the Data Link Connector (DLC). It is located in the instrumentpanel fuse block. The DLC is used to connect the scan tool. Battery power and ground is supplied for the scantool through the DLC. CAN line is used to communicate with the other module such as the Transmission ControlModule (TCM) and Transfer Case Control Unit (TCCU).
Keyword 2000 Serial Data Communications
Each bit of information can have one of two lengths: long or short. This allows vehicle wiring to be reduced bytransmitting and receiving multiple signals over a singles wire. The message carried on KWP 2000 data streamsare also prioritized. If two messages attempt to establish communications on the data line at the same time, onlythe message with higher priority will must wait.

IMMOBILIZER
YAD1F630
Circuit DescriptionImmobilizer is a device disabling vehicle ignition unless a specific key is used and designed to help preventvehicle theft.
Immobilizer is comprised of two devices, a key with encoded transponder and ECM with the same encoding ofthe transponder. When a key is inserted into the hole to start vehicle and turned to ON, the ECM reads anddecodes the transponder code and, if the same, starts the engine, it is called immobilizer. It means immobilizersystem disables starting by stopping fuel supply if the code in the transponder does not match the code storedin ECM each other.

FUEL SYSTEM SPECIFICATIONUse Only Unleaded Fuel Rated at 89 Octaneor HigherFuel quality and additives contained in fuel have asignificant effect on power output, drivability, and lifeof the engine.
Fuel with too low an octane number can cause engineknock.
Caution: Use of fuel with an octane number lowerthan 89 may damage engine and exhaust system.
Notice: To prevent accidental use of leaded fuel, thenozzles for leaded fuel are larger, and will not fit thefuel filler neck of your vehicle.
Do Not Use MethanolFuels containing methanol (wood alcohol) should notbe used in vehicle.
This type of fuel can reduce vehicle performance anddamage components of the fuel system.
Caution: Use of methanol may damage the fuel sys-tem.
Vehicle Fueling from Drums or StorageContainersFor safety reasons (particularly when using noncom-mercial fueling systems) fuel containers, pumps andhoses must be properly earthed.
Static electricity build up can occur under certain atmo-spheric and fuel flow conditions if unearthed hoses,particularly plastic, are fitted to the fuel-dispensingpump.
It is therefore recommended that earthed pumps withintegrally earthed hoses be used, and that storagecontainers be properly earthed during al lnoncommercial fueling operations.
